Welcome to Daihl's, formerly Daihl's Surplus
Thank you for visiting our web site! Here you will find manuals and free software. Most of the manuals are operation and maintenance manuals for US Government surplus electronic equipment. There are also manuals and schematics for telephone station equipment, from back in the day when AT&T had a government granted monopoly on telephone service. Unlike today's cellphones, telephone equipment back then was designed for a 40 year life and 0.99999% service availability. Take a look, you may find something useful.
If you have an XM Direct satellite radio receiver, there is free PC software to control it. Check the Free software page.
